10 Secrets of Successfully Computerizing Your Business.

Be an educated buyer  There are so many ways to learn about computers and inventory pos system.  You can go to a library, browse the Internet, visit a local computer store or even another business that has a inventory POS system.
Know what you want from your point of sale software before you buy anything.   Make a list of functions you would like the point of sale system to handle.   Prioritize the list.
Buy only time-tested products.   Make sure that the inventory management software has been used in many businesses similar to yours and get references. Call the references.
Don't underspend.   Search for value, not price.   The price is important, but a good system is going to pay for itself many times over anyway.
Find a consultant that you trust and have confidence in.  Having a Value Added Reseller (VAR) or advisor to assist you with the implementation of a POS system will be well worth the investment.    The VAR should be familiar with the system and will be able to get you up and running quickly.
Don't try to automate your whole business in just one day, or even one month.  Take your time to get all the staff trained, and allow time to work out the kinks.  It can take a year or more to fully utilize the software.
Start fresh from the day you install the system.   Don't try to enter past history into the computer.  And generally, we don't recommend trying to put in accurate inventory counts on the very first day.  If your VAR recommends it, after analyzing your particular company, then we would defer to his expertise.
Back up your data daily.  Test the backup occasionally.   Keep a back up copy off site.
Buy a support contract from the POS vendor/VAR.  Keep current with upgrades.
Install a battery backup and dedicated electric line for your computer.  Power surges, summer outages due to heavy a/c use and other similar events occur regularly.  Clean, filtered electricity is as important a component of a successful point of sale system as anything else.
